Hewlett-Packard has performed another extreme act of corporate remodeling, firing its CEO Leo Apotheker after just 11 months and replacing him with billionaire businesswoman and political aspirant Meg Whitman. Yet it’s done little to convince investors that the company has its house in order.

HP has now removed two CEOs in two years, and the stock has dropped precipitously, shedding $60 billion of HP’s market value. Based on shareholder reaction to Thursday’s CEO shuffle, more punishment is likely in store.
